Rhode Island Department of Education Lesson Plan Lesson Title: Intermolecular Forces State Standards:(GLEs/GSEs) GSE - PS1 (9-11) - 4 National Standards: Context of Lesson: This class is after a class on polar and nonpolar bonds. In the last class the students were introduced to some forces in molecules and to dipole moments. In this class the students will go into more depth and learn about some new intermolecular forces. Opportunities to Learn: Depth of Knowledge: Prerequisite Knowledge: Plans for Differentiating Instruction: Accommodations and modifications: Environmental factors: Materials:
Objectives:
The students will evaluate the strength of intermolecular forces compared to the strength of ionic and covalent bonds.
Instruction: Opening:
Recap yesterdays class.
Talked about polar and nonpolar bonds.
Dipole moments.
Engagement:
Intermolecular forces.
Any idea what that means?
Hint: inter-
Forces between molecules.
Van der Waals Forces
Very weak forces
Dipole interactions.
We learned about dipoles, what do you think these are?
Lead students to define the term.
Reactions of a dipole in one molecule with a dipole in another molecule.
Dispersion forces.
The weakest intermolecular force.
The proximity of electrons to one side of a bond can change the arrangement of the electrons in the next molecule creating slightly polar reactions.
Hydrogen Bonds
What do you think a hydrogen bond is?
Bond between hydrogen and what?
This is a very strong dipole interaction.
Example.
Water.
Illustrate how a water molecule can have many hydrogen bonds.
What effects does this have?
Surface tension.
Holds the molecules together.
Closure:
In this class we learned about some intermolecular forces and connected them to what we already knew about dipole moments.
Next class we will review for the exam.
Bring in questions.
Assessment: This will be assessed on the unit exam. Reflections: (only done after lesson is enacted) Student Work Sample 1 – Approaching Proficiency: Student Work Sample 2 – Proficient: Student Work Sample 3 – Exceeds Proficiency:
